Master cylinder and brakes question for a 65 Dodge Dart

I have a 1965 Dodge Dart 270. I posted a picture of the slant 6 engine and many of you commented that I should consider upgrading my master cylinder to a dual Reservoir cylinder. Unfortunately comma the auto parts store close to me does not have anything listed for the Dodge Dart in a dual Reservoir cylinder. They also do not have a brake booster listed for that year as well. Do any of you have part numbers for other parts or both that I could have them search for? I would also like to eventually convert the front to disk brakes so any information on that would be helpful as well.
go to inlinetube.com and get the conversion that gives you the lines and distribution block, then go to your auto parts store and buy a drum/drum master cylinder for a 68 dodge dart... install, bleed, done deal
